    Abstract: Embodiments of the present disclosure relate to method and device for data processing in a communication system. For example, a method comprises: generating an error detection code for information bits to be encoded with a polar code, the error detection code being distributed in the information bits in a first order; determining, from among the information bits and the error detection code, a set of bits to be redistributed; redistributing a bit in the set of bits such that the error detection code is distributed in the information bits in a second order; and mapping the redistributed information bits and the error detection code to an input of a polar code encoder to be encoded with the polar code. Embodiments of the present disclosure further provide a communication device capable of implementing the above method.

    Abstract: Systems, procedures, and instrumentalities are disclosed for low latency data communications utilizing advanced coding via polar codes. An encoder may receive data traffic that includes different types of traffics such as URLLC data and control information. The encoder may sort the different types of traffics into multiple tiers of varying priorities. The encoder may map data included in the tiers to multiple bit channels of varying channel coding reliabilities. The encoder may receive a bit channel mapping rule indicating that a higher tier corresponds higher channel coding reliability. The encoder may dynamically receive the bit channel mapping rule such that the mapping of priority tiers to bit channels differs from one code block to another code block.

    Abstract: Methods for encoding and decoding Polar codes are provided, together with apparatuses for performing the methods. An encoding method combines first and second sequences of information bits and CRC bits and a plurality of frozen bits into an input vector. The input vector is multiplied by a generator matrix for a Polar code to produce a concatenated codeword. A decoding method receives such a codeword and produces a decoded vector by generating successive levels of a decision tree. For a first number of levels of the decision tree, paths beyond a first maximum number of most probable paths are discarded. For a second number of levels of the decision tree, paths beyond a second maximum number of most probable paths are discarded. In some cases, the decoding method may have improved performance compared to some decoding methods for non-concatenated codewords.

    Abstract: The present disclosure relates to a method for blind decoding a signal in a decoder of a mobile device. The method comprises receiving a channel coded signal; testing a plurality of hypotheses for the decoder that are not related to channel decoding by decoding the channel coded signal to generate a hypothesis specific decoded, channel coded signal and correlating a local channel coded reference sequence against a presumed corresponding section of the hypothesis specific decoded, channel coded signal for each of the plurality of hypotheses to generate a plurality of test results. The method further comprises determining a best hypothesis based on the plurality of test results and channel decoding a hypothesis specific decoded, channel coded signal for the best hypothesis to generate a channel decoded signal.
